ICE-CREAM FREEZER.

SPECIFICATION forming part of Letters Patent No. 410,773, dated September 10, 1889.

Application filed January 19, 1888. Serial No. 261,219. (No model.)

To all whom it may concern.-

Be it known that we, CHARLES G. SHEP- ARD and PETER ADAMS, of the city of Buffalo, in--the county of Erie and State of New York, have invented new and useful Improvements in Ice-Cream Freezers, of which the following is a specification.

This invention relates more particularlyto improvements in that class of ice-cream freezers which are provided with a hinged or movable top frame carrying a part of the actuating mechanism whereby the cream can or vessel is rotated, and which frame can be swung upwardly out of the way, so as to permit the removal and replacement of the cream-can.

Our invention has for its object to improve the construction of the hinged top frame,so that the driving-shaft and connecting parts can be readily removed for cleaning the same,

.also to provide the freezer with efficient means whereby the freezing-mixture is excluded from the actuating-gearing, and also to improve the fastening whereby the movable top frame is locked in position.

The invention consists of the improvements which will be hereinafter fully set forth, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a sectional elevation of an ice-cream freezer provided with our improvements. Fig. 2 is a front elevation of the fastening whereby the free end of the hinged top frame is secured to the tub of the freezer. Fig. 3 is a vertical section in line as a, Fig. 1. Fig. 4 is a bottom plan view of the top frame of the freezer and connecting parts.

Like letters of reference refer to like parts in the several figures.

A represents the outer wooden tub or vessel, which receives the cream-can B and the freezing-mixtu re. The cream-can is provided at its, bottom with a stud or journal, which turns in a socket or bearing arranged in the bottom of the wooden tub in a well-known manner.

C is the cover of the cream-can, and D the vertical shaft or spindle to which the dasher arms or blades are attached, and which is supported at its lower end in a bearing formed in the bottom of the cream-can and passing with its upper portion through an opening (1, formed centrally in the cover C.

E represents the movable top frame of the shaft f is supported. The latter is provided at its inner end with a bevel-wheel f, which meshes with a gear-rim f formed on or secured to the upper side of the cover C of the tachable hand-crank for turning the shaft.

The movable top frame is composed of a central portion or plate eand radial supporting-arms c e and 6 The arms e are jouron the underside of the arm 6 and a removable cap If. The latter is secured to the lug by 'a screw *6. with lips or flanges 2", which overlap the ends of the lug and hold the plate against turning 'on the screw i.

K K represent collars formed on the shaft the shaft against lengthwise movement. By arranging the outer bearing h obliquely the lower portion of the bearing is located in advance of or beyond the upper portion there- Whereby the opening of the bearing is rendered elliptical or elongated in the direction of the inclined portion of the frame, while it is practically circular in a plane at right angles to the actuating-shaft. tion forms a sufficiently snug bearing to prevent vertical play of the shaft and permits at the same time the shaft to be tilted downwardly upon raising the top frame and by allowing the shaft to be drawn inwardly out of the out-er bearing upon detaching the freezer, in which the horizontal actuatingcream-can and at its outer end with a denaled in bearings g, secured to the upper end The The inner bearing 72., composed of a lug 71*, arranged The cap is provided at its ends 1'" between the bearings thereof, so as to hold of instead of directly underneath the same,

This construcremoving the cap of the inner bearing, there- 10 hand-crank. B y eonstructin g the outer bearing in this manner the same may be cast complete in one )iece with the top frame without the necessity of coring o'r drilling, and but one of the bearings need be divided or provided with a removable cap, thereby simplifying the construction of the top frame and reducing its cost and facilitating the removal and replacementof the shaft when it is desired to clean the machine. The shaft is attached to the top plate by removing its crank, passing the outer end of the shaft through the oblique outerbearing, then placing the inner portion of the shaft into the inner bearing and securing the cap of the same in place.

L represents a metallic plate secured to the side of the tub A near the upper edge thereof, and provided with a notch or recess 1, which receives a lip Z, formed at the outer end of the arm a of the top frame, and whereby said arm is held againstlateral movement.

M is a hook pivoted to the plate L and engaging over a hook-shaped lug m, formed on the lip Z of the arm c and whereby the latter is secured in its seat in the plate L.

n represents a dog or pawl pivoted to the plate L and bearing against the rear side of the hook M, so as to prevent the accidental disengagement of the hook from the arm 6 Upon throwing the catch 22 back the hook M can be released from the lug m.

liy attaching the parts of the fastening to the metallic plate L the formation of the usual notch in the upper edge of the tub for receiving the end of the arm 6 is dispensed with. A more rigid lock is also obtained by this construction, as the notch or socket in the metallic plate does not wear and allow the arm to become loose in time,whieh is the case when the socket is formed directly in the wooden tub, because the sides of the socket are caused to become soft and decay by contact with the freezing-mixture and allow the socket to enlarge.

The upper square end of the dasher-spindle D is inserted in a correspondingly-shaped opening in the top frame in the customary manner and forms a support upon which the upper end of the cream-can turns.

P is an upwardly-projecting collar or annular flange formed on the upper side of the cream-can cover at a distance inwardly from the marginal flange of the cover and surrounding the gear-rimf 0 represents a depending annular flange or shield formed on the under side of the central portion (2 of the top frame and overlapping the collar P. The shield, in conjunction with the (30llit1,f0l'lll5 a guard, which prevents the freezing-mixture working over the top of the can from entering between the gearing and interfering with the easy operation of the freezer.

By arranging the collar and shield above and within the upper marginal edge of the can the freezing-mixture can be packed to the extreme top of the can without danger of interfering with the actuating-gearing, thereby enabling the full capacity of the creamcan to be utilized. The collar of the creamcan cover also forms a convenient handle for manipulating the cream-can.

\Ve claim as our invention- 1. The combination, with the tub, the creamcan provided with a gear-rim, and the actuating-shaft provided with a wheel, of a removable top frame provided with a divided inner bearing and a solid oblique outer bearing, in which the shaft is journaled, whereby the shaft can be tilted and withdrawn from the solid outer bearing upon removing the cap of the inner bearing, substantially as set forth.

2. The combination, with the tub, the creamcan provided with a gear-rim, and the actuating-shaft provided with a gear-wheel, of a removable top frame provided with a divided inner bearing and with an outer bearing having its lower portion arranged outwardly beyond its upper portion, substantially as set forth.

3. The combination, with the tub, the creamcan, and its cover provided with a gear-rim, of an upwardly-projecting-collar secured on the cover within the marginal edge thereof and surrounding said gear-rim, a removable top frame adapted to be secured to the tub, a shaft journaled in said frame and provided with a gear-wheel meshing with the gear-rim of the cream-can and rotating the same, and a depending annular shield arranged on the under side of the top frame above and inside of themarginal edge of the crea1ncan and around the collar thereof, substantially as set forth.

\Vitness our hands this llth day of January, 1888.
